背景：本次回顾性横断面研究调查了未完成推荐牙周治疗疗程的受试者5-18年的治疗结果。方法：回顾65名自愿停止治疗的受试者。研究对象的人口学数据和牙周治疗停止后的牙科病史通过问卷调查的方式收集。结果：随着时间的推移，共有229颗牙齿脱落，主要原因是牙周原因。上颌磨牙和下颌磨牙缺失最多。牙齿脱落率(每名患者每年0.38颗)与未经治疗的患者相当。观察到牙周健康恶化，表现为探诊时出血部位(BOP)和再次检查时探诊袋深度(PPD)大于或等于6 mm的部位百分比增加。牙齿缺失与：(I)停止治疗的年限；(Ii)停止治疗前PPD大于或等于6 mm的部位的百分比；以及(Iii)重新检查时的PPD呈正相关。牙周PPD大于或等于6 mm的部位百分比与牙周牙缺失呈正相关，与无BOP的部位百分比呈负相关。结论：随着时间的推移，未完成牙周治疗的患者有进一步牙齿脱落和牙周状况恶化的风险。
Background: The current retrospective cross-sectional study investigated 5-18-year treatment outcomes in subjects who did not complete a recommended course of periodontal therapy.Methods: Sixty-five subjects who voluntarily discontinued therapy were recalled. The subjects' demographic data and dental history since discontinuation of periodontal treatment were collected via questionnaires. The subjects' periodontal condition, radiographic data and individual tooth-based prognosis at pre-discontinuation and recall were compared.Results: A total of 229 teeth had been lost over time, mainly due to periodontal reasons. Upper and lower molars were most frequently lost. Rate of tooth loss (0.38/patient per year) was comparable to untreated patients. Deterioration in periodontal health in terms of increased percentage of sites with bleeding on probing (BOP) and sites with probing pocket depths (PPD) of 6 mm or more at re-examination was observed. Positive correlations were found between tooth loss and: (i) years since therapy discontinued; (ii) percentage of sites with PPD of 6 mm or more at pre-discontinuation; and (iii) at re-examination. Percentage of sites with PPD of 6 mm or more at recall was positively correlated with periodontal tooth loss and negatively correlated with percentage of sites without BOP.Conclusions: Patients not completing a course of periodontal therapy are at risk of further tooth loss and deterioration in periodontal conditions over time.
